dear pw vitz owners
i bought vitz 2006 i have changed all necessary things.like
engine oil,trasmission oil cvt,oil filter,air filter,denso japanese plugs,remvoed catayic converter & also one stp injector cleaner.
now my problem is.
1=there is so much noise within cabin it comes from engine is it normal?
if it is not then how can i eliminate this noise.
You will have to live with this noise as it is characteristic of 3-cylinder models (2005+). One way to reduce this noise is by turning the music player ON
2=after removing catalyic converter how to make it smooth, noise less like zero meter car.
After removing CAT, your car will become much louder and can be easily smelt from 200 meters due to exhaust smell. Don't remove it, but if you must, then check PW Naweed's method of removing CAT.
3=there is knocking in engine even 40,60 percentage of high octane
how can this knocking get finish i am very irritating of this.
My 2009 vitz doesn't knock even with 100% regular fuel from PSO. Change your petrol pump and see the result. In idle condition, vitz knocks a little while AC is ON, otherwise no knocking at all at speeds greater than 10kmph. These japanese cars are very sensitive w.r.t fuel quality, which is often poor at our petrol pumps.
4=fuel average even after changing denso plugs is 10 km/lieter without ac
how can i improve this fuel econmy...
Get your engine's throttle body cleaned. Improve your driving habits (google it). And most importantly, keep 30psi pressure in both front and rear sets of tyres. Maintaining this pressure alone will give you a boost of about 2 kmpl, tried and tested! Always use genuine toyota air filter. Check the condition of current one and replace if required. Clean cabin AC filter to minimize cooling/heating requirement. When I purchased my car, it was giving me 8 kmpl, but masha Allah now it is giving me 14 kmpl in town.
please please help me out i insisted my father so much to buy vitz but now i cannot ask him that i want to change the car and cannot describe him these problems as he had spent i million ruppes hard earned money.
